Use AppWizard font in emWIn

How do I access the AppWizard font in emWin?

I see the variable acArial_24_Normal_EXT_AA4 is used for the "Arial_24_Normal_EXT_AA4.xbf" font. I see the AppWizard API call APPW_GetFont().

I cannot seem to get APPW_GetFont() to return 0 (success). No combination of using the window, widget IDs (or handles) seems to fill the GUI_FONT structure.

C Source Code

GUI_FONT FONT24; // global font variable
...
// ID_SCREEN_00, ID_BUTTON_00 - crash
// hScreen00, hButtons[0] - 1
// 0, 0 - 1
// ID_SCREEN_00, hButtons[0] - 1
// hScreen00, ID_BUTTON_00 - 1
dlog("APPW_GetFont() => %d", APPW_GetFont(ID_SCREEN_00, ID_BUTTON_00, &FONT24, acArial_24_Normal_EXT_AA4));

where ID_SCREEN_00, ID_BUTTON_00 are the AppWizard IDs.

It appears I need the GUI_XBF_DATA structure rather than the raw XBF array. Where do I get access to that guy?

Cheers,
Joe

Hi,

the last parameter of APPW_GetFont() needs to be a pointer to a GUI_XBF_DATA structure instead of to an array of XBF data.

Best regards,
